White Knight Pre-Filters

Protect pumps from wafer shards and harmful debris

Overview

White Knight Catcher™ pre-filters protect components from debris. They feature larger through holes than other pre-filters to avoid loading filters with fine crystals while still filtering solids that could damage pumps. The filter can be removed and cleaned without disconnecting liquid lines. White Knight pumps damaged by passing solids while using Catchers™ are repaired under warranty.

Pump Mounted

Use between inlet port and fitting.
